"power" is a very subjective and problematic measure. We're discussing Turing complete languages and nothing prevents me from implementing a compiler/interpreter from one language to another thus gaining its "power". 
What we really want to talk is ease of expressiveness.
C++ is more complex than D which means its harder to express oneself in c++. The difference is not that you can express something in one language but not in another (Both are Turing complete) but rather the *difficulty* of expressing the same thing in both languages.

That difficulty makes for a steeper learning curve.
